Deployment Success

I have an AHV VM that I would like to disconnect the NIC and connect the NIC in my script.  I need it disconnected while sysprep runs and sets a static IP address then I’m good to connect the NIC again.  (Otherwise it pulls a DHCP address and replaced the hostname with the DHCP address in DNS).   I can Get-NTNXVMNIC and see the current status of the NIC but I don’t see a way to change the status (i.e. I don’t find a Set-NTNXVMNIC command).   Thanks!   -TimG

Hi, Does anyone know exactly how many nodes can I install by Foundation 4.5 at one time? As I am going to write some internal docs related to Foundation so I do want to know.   Thanks.

NTP or Network Time Protocol is an integral component for any infrastructure as it allows for accurate timestamps of events across the environment. Whether it is relied on for monitoring, troubleshooting or services and applications operations – NTP source is one of the key components of modern IT infrastructure.it helps different systems to be in sync with each other.   Controller Virtual Machines (CVMs) are the backbone of Nutanix Hyper-converged Infrastructure. It is important for all the CVMs in the cluster to be in sync with each other. The CVMs use NTP to sync time between themselves within the cluster by after electing one of the CVMs as an NTP leader, even when an external NTP server is not configured, not available or not being used by design.    Is there a check which validates time sync between the CVMs? 

The Nutanix CVM is what runs the Nutanix software and serves all of the I/O operations to the hypervisor and all VMs running on that host hence it is of crucial importance to configure CMVs with the right amount of resources. The RAM and CPU allocation of the CVM both depend on the model of the nodes, the storage capacity of the cluster and the features used in the cluster. Each environment is unique in a way and each and every single one is dynamic by nature. Features are turned on and off, nodes upgrade, storage added. The following guide helps us to understand the memory requirement of the CVM for different models and features. The next time you are planning to add a feature or upgrade hardware in the cluster look at the minimum requirements to make sure that the cluster performance is not affected. After all there are very few things more satisfying than a smooth maintenance window.

Hello, We build our vm images using packer and ansible and upload them to different endpoints. First time I uploaded the images to Prism Central using API v3 and batch processing. Prism Central deploys the image to all the cluster that are registrated. That works fine… BUT… HOW can i define the destination storage container on each cluster?? I can define placement policies etc but I cannot assign a category or policy to Storage Container. Prism Central always deploys the images to “SelfServiceContainer”. But we dont want that.

Hi everyone,I’m using the API to pull VM performance stats, however I’m having trouble interpreting what I’m seeing.For instance, I’m pulling “hypervisor.cpu_ready_time_ppm” for one of my VMs and getting the following output:{ "statsSpecificResponses": [ { "successful": true, "message": null, "startTimeInUsecs": 1576458000000000, "intervalInSecs": 30, "metric": "hypervisor.cpu_ready_time_ppm", "values": [ 108, 97, 144, 107, 89, 92, 78, 74, 47, 49, 90,.... Output truncated for brevityI get that the metric is a percentage but obviously you can’t have 144% of time, so how should I interpret these values?What I really need is a guide and/or reference that explains all of these metrics and how to interpret them.I found the following link but it doesn’t really tell me what I want to know:

When it comes to administering the Nutanix cluster, it's very important to control permissions and to restrict access to critical components such as CVMs, AHV hosts and the Prism UI. Any user that has write access to these components can make drastic changes to the Nutanix environment and thus to your organization’s production/testing environment. Here is how to reset the password for each of the components above: AHV | Root account password reset check out KB-7068 Reset Web Console or nCLI Password check out KB-1200 To recover CVM Password Through the Prism Web Console check out KB-2233

Nutanix recommends that you use a single container in an AHV cluster to simplify VM and image management. What if you still have to have more than one container and wish to split existing VMs between the containers?  For example, you created a container named Production and want to move all production VMs to that container.   Since currently there is no Storage vMotion equivalent available to move VMs between containers, what we do as a workaround is that we create images from the vdisk and then use these images to deploy new VMs and selecting the desired container.   A general overview of the process looks this: Find the VM disk files.

Hello All, i have a question want to explain  what’s the differents between IPMI port and SHARED IMPI? if there are any business or technical cases to choose between them ?    thank you,

Our hosts network ports are currently configured as Active-Backup bonds. I can determine which Ethernet port is currently active, which Ethernet port is on standby, and I can issue a command to failover the port. I would like to know if there is a command which can be run from the AHV which outputs the time and date-stamps of the last Host Ethernet port failover. 

There are various scenarios in which you may need to unregister a cluster from PC, and it is important to do it correctly.  Whether you are decommissioning a Prism Element (PE) cluster which was registered to Prism Central (PC), or you already have decommissioned a cluster but it is still linked to a PC, or you have a cluster that is registered with one PC instance but would like to re-register it with a different PC instance for the benefit of localized management or to configure availability groups using Leap. All    What does "correctly" look like? Done properly, unregistration of a cluster from PC involves a remove-from-multicluster step f

What is LCM? The Life Cycle Manager (LCM) tracks software and firmware versions of all entities in the cluster, integrated both on Prism Element and Prism Central. LCM Structure: LCM consists of a framework and a set of modules for inventory and update. LCM supports software updates for all platforms that use Nutanix software. LCM supports firmware updates for a specific platforms. From Prism Element you can use LCM to update AHV, NCC, Foundation, BIOS, BMC, DATA Drives, HBA Controllers, SATADOMs and M.2 Drives (G6 and later). From Prism Central, you can update Calm, Epsilon, Karbon, and Objects.   When you run a firmware upgrade on multiple nodes, the LC

Dear all, I need to provide some reporting for my management. I'm using REST API & Python, to extract values. I managed to get hosts information (cpu, ram) and physical storage without any problem. Now I need to get the logical storage summary and I can't find the values via the REST Api. (same values as we get on the PRISM homepage on Storage Summary part) It's probably a calculation but I can't find the right one. May I ask you to provide me the values and calculations. Thank you for your help. Best regards Cedric

What is Nutanix Guest Tool (NGT)? Nutanix Guest Tools (NGT) is a software based in-guest agent framework which enables advanced VM management functionality through the Nutanix Platform. The solution is composed of the NGT installer which is installed on the VMs and the Guest Tools Framework which is used for coordination between the agent and Nutanix platform. The NGT installer contains the following components: Guest Agent Service Self-service Restore (SSR) aka File-level Restore (FLR) CLI VM Mobility Drivers (VirtIO drivers for AHV) VSS Agent and Hardware Provider for Windows VMs App Consistent snapshot support for Linux VMs (via scripts to quiesce) This framework is composed of a few high-level components: Guest Tools Service Guest Agent

Hi,I have a customer with multiple clusters running hyper-V 2016. We are noticing dropped RX packets in the clusters. There was to an extent where there was a RX dropped packets alert generated in one of the clusters. So we proceeded to upgrade the Intel NIC firmware as recommended by support, after this, we notice the alert does not happen anymore. But we still see dropped packets.Is this normal or okay for a cluster/NIC to have rx dropped packets?

What is Foundation? Foundation is a Nutanix provided tool leveraged for bootstrapping, imaging and deployment of Nutanix clusters. The imaging process will install the desired version of the AOS software as well as the hypervisor of choice.   By default Nutanix nodes ship with AHV pre-installed (depending on your country), to leverage a different hypervisor type you must use foundation to re-image the nodes with the desired hypervisor. NOTE: Some OEMs will ship directly from the factory with the desired hypervisor.   The figure shows a high level view of the Foundation architecture:     To use a different hypervisor (ESXi or Hyper-V) on factory nodes or to use any hypervisor on bare metal nodes, the nodes must be imaged in the field. Foundation service is includ

SAS is the leader in analytics and Nutanix is the leader in invisible infrastructure. Nutanix has thousands of customers and many of them already have SAS software running in their organization. They have experienced the benefits of invisible infrastructure and are moving more of their applications (including SAS) to Nutanix. It’s easy to deploy and manage SAS 9.4 and SAS Viya on Nutanix Today, SAS 9.4 helps discover insights, manage data and make analytics approachable. SAS 9.4 has been tested on Nutanix NX Models – both as a hyper-converged infrastructure (HCI), as well as using Nutanix as back-end storage only, for external hosts. Nutanix AHV clusters perform well in both scenarios.

For most maintenance tasks and upgrades we can keep the cluster up and VMs running, but in some cases the whole cluster will need to be shut down. If you just need to power off a single node, a cluster of three or more nodes won’t need to stop.  To stop a single-node cluster please see the section “Shutting Down a Single-node Cluster” in the NX and SX series hardware administration guide. To stop a single node in a larger cluster see the section “Shutting Down a Node in a Cluster (AHV)” 

Regardless of the reason to destroy the cluster whether it is to relocate and reuse an existing kit or switch to a different hypervisor, to build something new often means to destroy something that already exists and Nutanix has a process for it. Migrate all user VMs off the cluster. Reclaim licenses. Ensure there are no errors displayed.  Stop the cluster. Destroy the cluster. Not too bad, right?   Some things to keep in mind is that cluster

Hi, I’ve configured a Nutanix device running Prism 5.10 with SNMP - I’ve set a transport for UDP on port 161 and made sure there’s a tick in Enable for Nutanix objects.  But when I try to run an SNMPWalk or SNMPGet from a device on the same subnet to start building a custom service in Solarwinds NCentral I get no response from the device.  To confirm the issue isn’t on the server I’m running the query from I’ve done the same thing to another windows server and that works fine, so I’m fairly confident I’ve got the local firewall configured, I’m just not getting a response from the Nutanix device? I configured a trap on the Nutanix device and pointed that at the same server and that worked, it just doesn’t seem to be responding to incoming SNMP requests?  Any suggestions as to what I may have missed would be gratefully accepted!

Let say that you have updated your IPMI IP address or moved it to another subnet, after you finish the update you are not able to log back in to the IPMI. This happens as a result of not restarting the genesis service on the local node which people tend to forget, after you make the change you must restart the services on the same node’s CVM by running “genesis restart”. If the restart is successful, output similar to the following is displayed: Stopping Genesis pids [1933, 30217, 30218, 30219, 30241] Genesis started on pids [30378, 30379, 30380, 30381, 30403]   You can change the network configuration of your IPMI using one of the following methods:
